Hey folks, im hoping someone can help me out as im at my wits end here.
When i first got my phone i was able to install TWRP and root the phone and install a custom rom.
Then i downloaded the latest version of Twisted mate 8 and used TWRP to install it and for whatever reason when the phone went to reboot it put me into EMUI recovery and forced me to install the latest version with recovery.
Now that my phone is cllean slate, im trying to install TWRP and with no success. My bootloader is still unlocked but no matter what process i use, wether its ADB or SRK tool kit, after i do the cmd entry and it says its been installed, when i try to reboot into TWRP (holding volume up with power) I get EMUI.
its as if the latest version of EMUI is preventing me from installing TWRP again.
Does anyone know what could be the issue.
also can anyone recommend a site that has a clear simple step by step guide to rooting this phone?
I need to install Twisted Mate 8 or Kang VIP ASAP.
Thanks
Yeah. Install twrp manager from play store and try to reboot from there. But both volume buttons at start and release them almost immidietly

I was finally able to install TWRP but when I enter TWRP and it first asks me for a code for the encrypted data, which I never encrypted, and when I bypass that and try to install an img all the storage options say 0 mb

Hi spinward,
You have to format data with twrp. Don't forget to save it first and restore it after formating.

I've done the format in TWRP and nothing changes, except the stock ROM is reset.
When i enter TWRP again the partitions/hd all say 0mb still
Flash TWRP via TWRP and see
Hi,
I think I ran into the same problem while updating my AL-10 from B172 to B361 and all the detours one has to make during that update trajectory.
After flashing TWRP, you have to reboot but make sure your phone isn't connected with USB-cable to your computer. That did the trick for me

Hello all,
I unlocked the Mate 9's bootloader,
Installed TWRP,
Rooted it with shh's superuser.
I was planning to try and restore to factory to make a clean backup before rooting it again.
I used TWRP to wipe in preparations to start re-installing. Using eRecovery (can't retrieve info from server) or manually installing the update.zip seems to fail. After looking through some threads I have found FunkyHuawei. This allowed eRecovery to find a file, download it and (apparently) start restoring from it. However, it is now (still) stuck trying to boot, failing and going back to EMUI's eRecovery.
Any ideas how I can get my Mate 9 back to a usable condition?
Edit 1:
TWRP is removed now (replaced by default recovery)
Fastboot reports it is locked once more.

As mentioned in FunkyHuawei's instructions, hold volume up key with no usb plugged in while booting, and choose to wipe data and cache. Then, phone should boot.

I wiped the cache partition, sadly after trying to boot, it rebooted and went back to eRecovery.
Edit 1:
In my need to press all buttons I also clicked wipe data/factory reset. This seems to have worked, now in the default setup menu.

FunkyHuawei is really helpful when soft bricked! I also unlocked bootloader, rooted & install TWRP.
But it seem OTA would be failed to install and it lead to OTA with full image, then it become soft bricked!
Everytime I used FunkyHuawei, it can do full recovery with locked bootloader again and go through unlock & rooting again.
Not easiest when you want latest firmware with rooting but it still works.

It mostly went ok, but it appears that some system parts are missing...
e.g. Themes are not working anymore and the 'messages' app seems to have some alternate icon (low res, strange smiling text bubble)
US BLN-L24 on straight talk here. I've spent months trying to figure out a painless way to get this thing upgraded, rooted, and rom'd but 100 different threads explain 100 different processes and none of them are particularly easy to follow. Surely someone has taken the time to write up an updated, easy to follow guide for this specific model of 6x? Does this still require debranding?
Model number = BLN-L24
EMUI Version = 5.0.4
Build Number = BLN-L24C567B377
Android version = 7.0
Thanks.

There is. But yeah I agree. Anyway to debrand and update to EMUI 8 you need to follow a few steps.
You need an Unlocked Bootloader. If yours isn't unlocked, unlock it via Ministry of Solutions or DC Phoenix. Both are paid.
You need an SD card with at least 8 GB size.
First of all download Firmware Finder from Play Store. Search for model BLN-AL20 and download the 8.0.0.536 Full-OTA. Download the following three archives:
Update.zip
Update_data_full_public.zip
And the last one should be the one with BLN-AL20 in the name.
After you download the three files, go ahead and search for HWOTA for Honor 6X on XDA and download it. Extract it to /C. Once extracted, rename the files you downloaded before to:
Update.zip -> Don't rename
Update_data_full_public.zip -> update_data_public.zil
And the last file to -> update_all_hw.zip
Transfer the three files to update folder inside HWOTA 7. Now, you need an unlocked Bootloader. Now boot phone into Fastboot and connect phone to PC. And now run update.bat once it asks you to boot into TWRP unplug your phone. Now hold power button. When it boots up and you see three options menu, hold volume up to enter into TWRP. once in TWRP reconnect USB cable. Now press Enter twice. Wait patiently. Once it finishes, reboot phone and when you see three options menu, again hold volume up to boot into eRecovery. Perform a Factory reset. Once that complete, Format Cache and reboot. First boot will take several minutes. On first boot it will be an incomplete flash. You won't have any signal. To fix that, download Hurupdater. Search for it. Once it's download transfer it and the same three files you used before to your SD card inside the same folder. Next download TWRP from link:
https://mega.nz/#!a81EDZAR!2-9yPFh3reghkGcfSl3nRIJhHGkP8fqDsgUG66ewjkk
Once TWRP is downloaded, again reboot to Bootloader and flash TWRP by command:
fastboot flash recovery_ramdisk RECOVERY-V2.img
Then reboot with fastboot reboot.
Once phone reboots, power it off. Next turn on by holding Power and Volume Up simultaneously till you boot into TWRP. Once in TWRP head over to
Wipe -> Format Data -> YES -> hit Enter
Once that finishes, press back twice. Now:
Advanced Wipe -> Mark Dalvik/ART Cache, Cache, Data, Internal and System. Swipe to Wipe.
Once wipe finishes head over to install, select SD card and navigate to folder with the Hurupdater files. Select only Hurupdater to flash. Press Volume Down when prompted. It will take at least 10 mins. So be patient. Once it finishes, Wipe Cache/Dalvik. After that, Reboot System Now. When it's booting and you see these options menu again hold into eRecovery and wipe Data/Factory Reset. Once that finishes again Format Cache and then Reboot System Now.
First boot will take at least 10 minutes. So be patient and don't panic. When your phone first boots you won't have any signal. Finish setup. Then turn off phone. Plug USB into computer and the other end into phone while holding Volume Down when it's powered off. Once you boot into Bootloader reflash TWRP as you did before. Next flash latest Magisk. Install Magisk Manager and ES File Explorer and Grant SU rights of ES File Explorer. Then using root Explorer navigate to
/cust/all/cn/prop/local.prop
And edit the line
ro.config.full_network_support=true
Change true to false. Save and reboot. Now you have Network. If this works then I'll help you flash a Custom ROM.
I saved my PID and unlock code from last year when I first tried to unlock/root/rom the phone, so no need to pay for bootloader unlock.
I just unlocked my bootloader and it factory reset my phone, now waiting for phone to boot so I can go to play store and continue with your instructions. Will report back soon, hopefully. I made sure all my photos and contacts were saved to external SD before unlock so no data lost.
Edit1: Downloaded/installed firmware finder, retrieving those 3 files now, then will move them to pc. Getting hwota extracted to C:\ right now.
Got stuck near the end of your guide;
Code:
C:\Users\John>fastboot flash recovery_ramdisk RECOVERY-V2.img
target reported max download size of 471859200 bytes
sending 'recovery_ramdisk' (9100 KB)...
OKAY [ 0.222s]
writing 'recovery_ramdisk'...
FAILED (remote: Command not allowed)
finished. total time: 0.232s
I put the recovery-v2.img file in C:\users\john\ directory, assuming it needed to be there since that's my working directory in cmd prompt when I submit that command.
I figured I would have to unlock bootloader again since it relocked from earlier, so I did that and went back to fastboot and ran fastboot flash recovery_ramdisk RECOVERY-V2.img again. Now I get this error,
Code:
c:\Users\John>fastboot flash recovery_ramdisk RECOVERY-V2.img
target reported max download size of 471859200 bytes
sending 'recovery_ramdisk' (9100 KB)...
OKAY [ 0.221s]
writing 'recovery_ramdisk'...
FAILED (remote: partition length get error)
finished. total time: 0.231s
Not sure what to do now?
Rebooted to recovery and had TWRP, noticed the update.bat window was still up waiting for me to hit enter once booted in to TWRP so I tried that. Flashed the three files I saved earlier, rebooted, now doing update install so it looks like I'm back on track and not finished yet.
Edit1: Performed factory reset, then wiped cache and rebooted. Phone is now booting. At this point it *Should* boot normally, no signal, then I can reboot to fastboot and continue with flashing twrp and last few steps.
Edit2: fastboot flash recovery_ramdisk RECOVERY-V2.img appears to have worked after booting in to fastboot. Then ran fastboot reboot, booting now.
Edit3: On this part my phone appears to be stuck on chinese language?
First boot will take at least 10 minutes. So be patient and don't panic. When your phone first boots you won't have any signal. Finish setup. Then turn off phone.

I'm trying to figure out how to get it to english so i can finish setup, shut down, get in tyo fastboot, flash twrp again, then boot in to that to flash magisk. Also do I get magisk manager and es file explorer in play store?
Edit4: Got it to english, finished setup, shut down, fastboot, reflashed twrp, reboot, shut down, enter twrp with volume up + power, sd card not showing up on computer to copy latest magisk so had to reboot system and put that file on sd(showing BLN-AL20 and EMUI 8!!!), shut down, enter twrp again, flashed latest magisk, rebooted to EMUI8, launched Magisk Manager(already present) and it downloaded/installed update and Magisk now shows latest version installed. Installed ES File Explorer from xda labs page via hisuite, shows installed but when launching it just goes to white screen so currently trying to figure that out so I can edit that file and restore cell service.
Edit5: Removed ES File Explorer since it's not working and went with MiXplorer, edited that file and saved, rebooted, now have service. Now ready for new rom!
Now that phone is unlocked, rooted, and on EMUI8 how do I go about flashing one of the official openkirin roms at https://openkirin.net/download/? Which one is most stable for daily use?
Edit: Also no google apps, so I'm very limited in using my phone until I can get one of the OpenKirin roms installed.

I used RROS and it was pretty stable with no major bugs. 99% daily driver. But you can see ignorable force closes here and there.
It's simple to flash all OpenKirin Roms. Just download the desired one, put it into your adb folder, boot your phone to bootloader/fastboot, type command:
fastboot flash system (filename).img
Regarding GAPPS if you're on Stock Chinese Oreo B536, just download the playstore apk from apkpure or any other source and install. It will work and you can then disable AppGallery.
OpenKirin Roms have everything included, Gapps too.
Edit: https://openkirin.net/user_guide/openkirin-rom-installation-instructions/
The detailed guide to flashing OpenKirin roms.
Went with LineageOS since I've always loved their roms, figured I'd try that one first. At step 15 I choose wipe data/factory reset, it reboots, I don't touch anything, and it loads to the black/red TWRP. It did this twice so the second time I did factory reset from TWRP and reboot system.
It then went to LOS boot, then "to start android, enter password" screen. Looked around on google, some people said clearing cache fixed that, rebooted to stock recovery, said data partition corrupted, factory reset again, rebooted, again went to that TWRP for some reason, factory reset in there, wipe dalvik/art and cache, reboot system, LOS boot logo, phone said it was encrypting, rebooted, LOS boot logo, encryption unsuccessful screen and option to reset phone, keep clicking RESET PHONE button and nothing happens. Was able to do a power button restart since LOS is partially working, same encryption unsuccessful screen with non-working RESET PHONE button.
How do I fix this? I think the problem is factory reset in factory recovery is not working, because when it reboots to start factory reset it instead loads to TWRP and factory reset never happens. Can't use phone at all at the moment.
Trying RROS next to see if that helps, but I did notice FRP UNLOCK wasn't on fastboot screen...not sure why? Maybe that is my problem? Bootloader is unlocked.
Edit: Flashed RROS, tried a factory reset from erecovery, rebooted in to twrp again. Tried to factory reset there and reboot, RROS loading screen, encrypting again, reboot, I'm now in rom setup wizard so maybe it's working now? Not sure if I'm still rooted, though or why fastboot stopped saying FRP unlock.

No frp on chinese oreo due to partial Gapps presence/support. That's not an issue.
Now the Wipe Data option.
Wiping data through TWRP decrypts data partition and wiping with stock one encrypts it. OS works with encrypted one. So after installing any OpenKirin Rom, do factory reset with stock recovery right after flashing the rom.
Now follow the instructions of flashing rom, after that flash and go to stock recovery, wipe/factory reset. Restart and it should work

That's the part that is broken for me, stock recovery factory reset. I click the button, type yes and hit the button, phone reboots but instead of booting to the factory reset process it reboots to twrp each time.
Right now I'm officially loaded in to RROS I'm assuming, but not sure if I should expect any issues since I never did do a factory reset from what I've seen so far.

I am SO sorry. I wrote the guide and went to sleep. Glad to know everything worked for you. Here Is the stock Recovery. Flash it in the same way you flashed TWRP. And then factory reset. I was writing instructions but look like someone beat me to them. Again, Sorry.
https://mega.nz/#!xiR2TYAB!kmt60JDRh4_7u37W56CEJZUuhcZvv6AefJiuadF1e9s
And if you want a Pie ROM just ask. I know a really good and stable one. I will help with that.
Right now everything seems to be working fine, RROS is working with no issues so far, getting all my apps/settings back in place. Unfortunately I can only add my work exchange email account(office365) to gmail on this rom, can't do exchange in the android e-mail app which sucks.
I know TWRP is still there on the "ramdisk" hiding, but I've done several shutdowns and restarts and it hasn't come back up so I think I'll leave it be. If it becomes a problem I can always flash the stock recovery again.

Again. I am SO SORRY. I shouldn't have been this careless. But if you want to be sure, just boot into fastboot, flash stock Recovery, reboot. Again boot to fastboot, flash ROM like you did before, this time boot into Stock Recovery and Factory Reset. Reboot and profit. And if you want Root, then flash TWRP like you did before, followed by latest Magisk.

No problem at all, worst case scenario I would have just gone back to stock firmware since I still have the files from last year when I tried rooting/romming and failed.
Everything seems to be working great though. RROS is real smooth and very customizable which I like. Just can't seem to figure out how to get the stock email app to allow exchange account, and how to customize the notification light.
Magisk Manager was present when I first loaded in to RROS, upon opening it did its updates/installs. Just ran a root checker and phone is rooted...so somehow it maintained root from when I did the EMUI 8 install. Should I have busybox installed? Will xposed work for me?
Thanks to the both of you for all the help. I'm so happy to finally have a good ROM on my 6x. :good:
Phone is all configured and running great, sorted out the fb messenger light issue, busybox running.
Is xposed compatible with this version of android yet? And if I wanted to try one of the other OpenKirin roms, what is involved in switching? Just flash the other rom and perform a stock recovery wipe/reset, or do I need to wipe data before flashing new rom?

No. No Xposed. And to switch ROMs, flash the new one via fastboot followed by a factory reset in stock recovery and you're Golden

Awesome. I might give LOS a try tonight, depends on how attached I am to RROS by then. I've been playing with my phone all day at the office tweaking and change stuff in RROS getting everything working just the way I like it. I'm so thrilled to have the phone rooted/rom'd!
Thank you again for all your help!

Hi guys. I rooted my phone after purchase about two years ago using https://forum.xda-developers.com/mate-9/how-to/guide-how-to-root-mate-9-decrypt-data-t3569986
I am still running the same version now
Twrp
Model: MHA-L29
Build: MHA-L29C567B183
EMUI: 5.0
Android Version: 7.0
Any one got suggestions and steps to get to a newer version. I think I need to switch back to Erecovery etc but if someone had some exact steps and a good version to move to would be great. I had thought about installing magisk but my main concern is being able to run games like Pokemon go or Mario kart and they seem to be detecting my root. Not even sure having root is worth it anymore.
I installed stock recovery and did ota updates.. working like a champ!

Did you really flash TWRP to eRecovery? It is possible but people usually (specially if not installing Magisk on EMUI 9) flash TWRP to (EMUI) Recovery - which is not the same as eRecovery
So, do two tests:
- switch off
a) disconnect any USB
- press and keep pressing Vol+
- boot by Pow
In test b), do the same but with the phone connected to charger.
If it boots to TWRP in case a), then you flashed TWRP (as usual) to EMUI Recovery.
But if it boots to TWRP in case b), then you really flashed TWRP to eRecovery
If you have stock eRecovery, then in case b), once booted to eRecovery, do not accept Install latest or Factory reset, just Reboot or Shutdown
---
If you rooted by SuperSU, find an option like Full Unroot, or google for and find a zip for TWRP for unrooting - do unroot
Maybe, there are similar options for unrooting from phhSuperUser
Do not accept any OTA yet - if it comes
---
Install Firmware Finder app (from Playstore or from its thread on XDA).
Open, it will show firmwares for your MHA-L29C567
Scroll to the bottom to find your b183. Must be FullOTA-MF or FullOTA-MF-PV (2017.03.22)
Download its update.zip file, copy to PC, unzip to get update.apk - open it by Huawei Firmware Extractor (find its thread on XDA, read how to use it)
Extract Recovery.img (if you need to restore stock Ramdisk) or Recovery2.img (if you really need to restore stock eRecovery)
Extract also Boot.img
Flash Boot.img to Boot and Recovery.img to Recovery (if restoring Recovery), from TWRP or from Fastboot (similarly as you flashed TWRP from Fastboot back then)
Or, flash Boot.img to Boot and Recovery2.img to eRecovery, if you need to restore eRecovery
Now you should have stock Recovery and stock eRecovery - both tests a) and b) must not boot to TWRP
Also, you should have stock Boot - boot to system, check with RootChecker - there must be no more root
----
Have a proper SIM card and WiFi connection, go to Settings, System, Update, go to its menu and take the option to get Full OTA package
If it doesn't give you OTA update, boot to eRecovery (option b) as above, phone connected to the charger) and take Install latest firmware and recovery. Follow by Factory reset, only then boot to system
If eRecovery also fails to update from b183, you can try to update by HiSuite - it has also an option to choose installing a firmware
---
If it still fails to update, you can download by Firmware Finder b190 FullOTA-MF-PV (2017.10.31)
Download both zip files, do not unzip, copy them as downloaded to DLOAD folder on SD card (not Internal memory)
Switch off, press and keep pressing both Vol+ and Vol-, then boot by Pow
It should update to b190, and hopefully you will start receiving OTA updates for Oreo and Pie (must have SIM card)
If not - to be cont.
